The new specieshas been given a new scientific name -- Varanus bitatawa -- in recognition of its distinctiveness.
"We hope that by focusing on protection of this new V. bitatawa, conservation biologists and policy makers can work together to protect the remaining highly imperiled forests of northern Luzon," said Dr. Rafe Brown, leader of the team that discovered the new species and curator-in-charge of the Herpetology Division, University of Kansas Biodiversity Institute.

Adding another name:  Betula alba. We want to be sure that in spite of multybyte characters offsets are shown correctly. Checking if it can expand V. provincialis into a name.'
